Building Alexa Skills on Replit

Replit provides an environment where users can easily build and host Amazon Alexa Skills. Even without an actual Alexa device, you can fully test it through the developer console's simulator or the mobile app.

The process works as follows:

• The user's voice is recognized as an Intent by Alexa Cloud through natural language processing (NLP).
• A POST request containing the recognized intent is sent to the Replit web server.
• After the Replit server processes the request, it sends the result back to Alexa Cloud, which delivers it to the user as speech.

Building a skill starts in the Amazon Developer Console. Select 'Custom model' and set the backend to 'Provision your own', then define the Invocation name and the Intent and Utterances that will trigger the user's request.

Previously, AWS Lambda was mainly used to host skills, but with Replit, hosting becomes very easy while also taking advantage of Replit-only benefits such as ReplDB, Always-on, and Multiplayer. Developers can quickly get started by cloning the Replexa template.
